内容简介
Medical Image Reconstruction A Conceptual Tutorial introduces the classical and modern image reconstruction technologies， such as two-dimensional (2D) parallel-beam and fan-beam imaging， three-dimensional (3D) parallel ray， parallel plane， and cone-beam imaging. This book presents both analytical and iterative methods of these technologies and their applications in X-ray CT (computed tomography)， SPECT (single photon emission computed tomography)， PET (positron emission tomography)，and MRI (magnetic resonance imaging). Contemporary research results in exact region-of-interest (ROI) reconstruction with truncated projections，Katsevichs cone-beam filtered backprojection algorithm， and reconstruction with highly undersampled data with/o-minimization are also included.
This book is written for engineers and researchers in the field of biomedical engineering specializing in medical imaging and image processing with image reconstruction.
